My business partner is convinced that having a video on a page is inherently good for SEO and will improve its ranking. I'm trying to find some evidence to confirm or deny this theory. My hunch is that answers to questions like this are right on the money: videos are like any other form of content. Good content will drive traffic (and therefore links, and therefore SEO), bad/irrelevant content won't.
Does anybody know of any resources that have either confirmed or debunked the alleged inherent awesomeness of having a video on your page?
